I can't vouch for the system but the two orders I've placed with them in the past have been prompt and error free. With any Toy Hauler, they recommend one of two installation methods. Either order an extension cable for the camera antenna to run it in front of the garage wall for better reception or order the 2 meter antennas for the monitor/receiver and camera.
I ordered their 2 meter antennas for the BOYO system which came with our Fuzion that suffered from poor signal reception. They worked perfectly.
Although this is not the system you are interested, there is more information about the challenges we face:
